However, the "model=acer" parameter can be passed on the boot command line to enable such support. Otherwise, it is quite common that the internal microphone does not work.
Well, adding the quirk label is fine, but this is no real fix. I can apply it with a different subject.
Anyway, it's not such quite common that the machine doesn't work without the model quirk any longer :) In most cases, we want to avoid the model quirk but fixing the pin configuration instead.
If the auto-parser doesn't work as is, please give alsa-info.sh output on your machine, and give the exact description what doesn't actually work. Then we can fix in a better way.
thanks,
Takashi
